摘要
钢筋锈蚀导致混凝土结构性能下降,使用寿命缩短。纤维增强复合(FRP)筋具有高抗拉强度和优异的耐腐蚀性能,在部分结构中可代替钢筋,以提升混凝土结构的耐久性。将FRP筋应用于混凝土结构中是未来发展的重要方向,但目前关于其抗剪性能及抗剪机理尚未阐述清楚。本文对国内外关于FRP筋混凝土梁的抗剪性能研究进行了总结与分析。
The corrosion of steel bar leads to the deterioration of the performance and the shortening of the service life of concrete structures.Fiber reinforced polymer(FRP)bars have high tensile strength and excellent corrosion resistance,and can replace steel bars in some structures to improve the durability of concrete structures.The application of FRP bars in concrete structures is an important development direction in the future.However,the shear behavior and shear mechanism of FRP reinforced concrete beams have not been explained clearly.Therefore,the research on shear behavior of FRP reinforced concrete beams at home and abroad is summarized and analyzed.
